I have a little application which uses the HighLine 1.2.0 gem: it’s  
worked  
perfectly under Windows and Linux. When invoked in Mac OS X, however, I  
get:

/opt/local/lib/ruby/gems/1.8/gems/highline-1.2.0/lib/highline.rb:576:in  
`get_line': The input stream is exhausted. (EOFError) from /opt/local/lib/ruby/gems/1.8/gems/highline-1.2.0/lib/highline.rb:596:in`get\_response’  
from  
/opt/local/lib/ruby/gems/1.8/gems/highline-1.2.0/lib/highline.rb:177:in  
`ask' from /opt/local/lib/ruby/gems/1.8/gems/highline-1.2.0/lib/highline.rb:272:in`choose’  
from lib2.rb:90:in `ask_action' from lib2.rb:22:in`initialize’  
from lib2.rb:21:in `initialize’  
from lib2.rb:303

when I try to read input.

This is ruby 1.8.4 (2005-12-24) [i686-darwin8.5.2].

I’d be happy to hear any ideas.

Thanks…

HighLine is developed on OS X, so it _should_ work OK there. 😉

This error was added recently as a “feature”, to allow user code to  
detect the end of a stream. (It was intended mainly for scripts  
reading from STDIN and wanting to notice a control-D/control-z  
keystroke.)

Can you show me a simple example of how you are feeding the script  
input when the error is triggered and the HighLine code involved?  
(You can email me privately, so we don’t disturb the list with our  
bug hunt.)
